Mechanical Squeezed-Fock Gravimeter
Rozhin Yousefjani, Saif Al-Kuwari
Levitated mechanical systems are promising candidates for quantum gravimetry, as gravity couples directly to their center-of-mass motion, enabling the large mass of a mesoscopic pa…
Nonlinearity-enhanced Quantum Sensing in Discrete Time Crystal Probes
Rozhin Yousefjani, Shaikha Al-Naimi, Saif Al-Kuwari +1
Discrete time crystals are non-equilibrium phases of matter in periodically driven systems, characterized by robust subharmonic oscillations and broken discrete time-translation sy…
Exponentially-enhanced Weak-field Sensing with Quantum Stark Localization
Rozhin Yousefjani, Saif Al-Kuwari
Stark-localized quantum probes have recently been shown to enable quantum-enhanced weak-field sensing with polynomial or super-polynomial scaling. In this paper, we show that the s…
Discrete time crystal for periodic-field sensing with quantum-enhanced precision
Rozhin Yousefjani, Saif Al-Kuwari, Abolfazl Bayat
Sensing periodic-fields using quantum sensors has been an active field of research. In many of these scenarios, the quantum state of the probe is flipped regularly by the applicati…
Thermal avalanches in isolated many-body localized systems
Muhammad Sajid, Rozhin Yousefjani, Abolfazl Bayat
Many-body localization is a profound phase of matter affecting the entire spectrum which emerges in the presence of disorder in interacting many-body systems. Recently, the stabili…
Review: Quantum Metrology and Sensing with Many-Body Systems
Victor Montenegro, Chiranjib Mukhopadhyay, Rozhin Yousefjani +4
The main power of quantum sensors is achieved when the probe is composed of several particles. In this situation, quantum features such as entanglement contribute to enhancing the…
